Excel Data Analysis & Coding

I have a collection of spreadsheets that need to be turned into clear, insight-rich visuals. The core of the assignment is data analysis and visualization in Excel, with an emphasis on polished charts and graphs. I’m happy to rely on any chart type—bar, line, pie, or others—as long as it communicates the story behind the numbers effectively.

Beyond the spreadsheet work, certain parts of the workflow will benefit from small utilities or scripts, and I’m comfortable using C, C++ or Python for that. If a quick Python script can clean the data faster, or a C/C++ snippet can speed up a repetitive calculation, please incorporate it. My priority is accuracy, clean visuals, and a smooth hand-off so I can update the files myself later.

Deliverables
• One Excel workbook per dataset, fully analyzed and formatted
• Dynamic charts and graphs embedded in each sheet
• Any supporting C, C++ or Python scripts with brief inline comments
• A short read-me explaining how to run or modify the code and refresh the visuals

I’ll supply the raw spreadsheets once we start; you return the polished workbooks and code. Let me know your estimated turnaround and any clarifying questions.
